IiUILDING-TILE.

Applieation filed November 22, 1920. Serial No. 425,684.

T 0 all whom it may concern Be it known that I, HERBIAN C. BLANK, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin a Buildin -Tile, of which the following is a specification.

This invention relates to building blocks or tiles, and has for one ofits objects to improve the construction and increase the heat and coldresisting qualities without material increase of expense or weight.

Another object of the invention is to produce a wall unit or tile havingmeans whereby the joints between the units are rendered air proof andinsulated against the passage of heat or cold.

With. theseand other objects in view, the

. invention consists in certain novel features of construction ashereinafter shown and described and then specifically pointed out in theclaim, and in the drawings illustrative of the preferred embodiment ofthe invention.

Figure 1 is a perspective view of one of the improved wall units ortiles.

Fig. 2 is a side elevation, partly in sec tion, of a portion of a wallconstructed of the improved wall units or tiles.

Fig. 3 is a plan view of a plurality of the improved wall units or tilesengaging end to end and without the bonding cement.

Fig. 4 is a perspective view of a modified form of the tile.

The improved wall units or tiles each con sists of a hollow open endedstructure, pref erably oblong in outline and each including side walls10 and 11, top 12, bottom 13 and a longitudinally directed dividing web14;,

the web being preferably thicker than the walls, as shown.

Formed in the end of each web lei is a groove or channel 15, andlikewise formed in the top and bottom walls are like grooves or channels16 and 17 the grooves or channels merging one into the other at theirends, thus forming a continuous groove or channel around each unit. 7

The vertical. end channels 15 form spaces to receive bonoing cement ormortar indicated at 18 while the longitudinal channels 16 and 17 formdead air spaces between the units.

By this simple means the units are united by air, moisture, heat or coldproof joints and the cells at the opposite. sides of the partitions orwebs maintained entirely and continuously separated, and circulation between the cells transversely of the wall prevented.

The channels or groove 15.are preferably rounded at their ends and thegrooves also preferably convex transversely to insure the more readyentrance of the mortar or other cement, thus insuring an air andmoisture proof mortar keyed joint.

When properly constructed the improved tile will not need furring orlathing on the inside to receive plaster, and can also be constructedwith exterior channels or grooves 19 to securethe requisite bonding ofthe plaster or stucco material.

In Fig. 4 the improvement is shown applied to a single cell tile, or onewithout the dividing partition. 1 y

The improved tile is adaptable to r all climates, or conditions ofweather, and will effectually resist the passage'of heat, cold ormoisture and is likewise sound proof and fire proof.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specificat on, but it wlll be un derstood that anymodifications within the scope of the claimed invention may be made inthe construction without departing from the principle of the inventionor sacrificing any of its advantages.
